There’s an interesting nuance related to this. If the battle starts with the AI troops' turn, then the initial time delays are always identical, which means that the picture at the beginning of the turn is also identical: units move in the same way, deal the same damage, and their morale changes or they experience fear in the same way.
This is very interesting. It seems that the “monster week” can somehow be trained for. I need to take a closer look at that map.
See my walkthrough of the map in this thread, message #2558

Walkthrough review, Chinese map
I described what happens with devil weeks there. Also, in the same review, it is described how important it is to randomize the desired setup in a specific battle. This is directly relevant to today's discussion.
